LAMP.

SPECIFICATION forming part of Letters Patent No. 331,933, dated December8, 1885.

Application filed February 2, 1885. Serial No. 154,710. (No model.)

To all whom, it may concern:

Be it known that I, ELIAS M. WRIGHT, a citizen of the United States,residing in Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Lamps, of which thefollowing is a specification.

The object of my invention is to produce a better, clearer light, todeodorize the flame while burning, and to give a better light with aless quantity of oil, all of which will be fully and clearly hereinaftershown, described, and claimed by reference to the accompanying drawings,in which- Figure 1 is a vertical section through the lamp in line X X,Fig. 2, cutting through all except the button and its supporting-rod,and wick-raising bar. Fig. 2 represents atop view of the lamp.

The bodya of the lamp may be constructed in anyiwellknown way and of anysuitable material.

a is the tube for receiving and holding the wick. It is secured in theusual way at the bottom a. of the lamp.

c is another tube for surrounding the wicktube, so as to leave anannular space for the wick a.

A tube, a is firmly attached to tube a at c by a flange, c. This tubefits in a depression, so that it may be readily lifted off or put on, aswill be seen by reference to Fig. 1 of the drawings. It is also providedwith the usual springs, c, for holding the chimney. Near the lower endof the tubular wick is another tube, 0. It is made short, and isprovided with inwardly-projecting pins or the equivalent thereof, forpreventing it from slipping up or down the wick, which fits within it,as shown.

0 represents a thin bar of metal rigidly attached to the tube 0. Its useis to raise or lower the wick.

It will be readily seen that, as the wick is fitted loosely on the tubea and secured from slipping within the tube 0 as the bar 0 is moved upor down the wick will be moved also; but as this is a well-known devicefor raising or lowering a wick and in common use, a further descriptionof it here is not required.

Below the bottom and base 0* of the lamp is a receptacle, c, for holdingwater. This receptacle is provided with a tube, d, either secured to itby asorew, d, as shown, or made smooth, so as to slip down intoatubeadaptedjsgg to receive and hold it centrally within the wick-tube.It is supplied with cotton wicking (1 or other similar material.

d represents a lamp-button, made either hollow or solid; but I prefer asolid button 0f copper. To this button is attached a copper stem, (1*,which is made to slip down into the tube cl through the center of thewick d It is made of copper, as being the best metal to conduct theheat, but wire or any other material may be used.

In this arrangement of providing vapor for the flame by the heat ofcombustion I am aware that other fluids beside water may be used; butwater is the fluidlprefer, as the heatfrom the oil of gas-flameaiiording the illumination is sufficient to decompose the hot steam orvapor into its original elements-oxygen and hydrogen-which in theirnascent state recombine with the elements of the odorous compounds 7arising from the vaporized oil in the luminous flame, and therebydeodorizing the noxious vapors which give the disagreeable odors ofincomplete combustion. These elements, oxygen and hydrogen, in thedecomposed state, by thus recombining with the hydrocarbon compounds inthe flame, produce an increased heat, thereby subjecting the freedparticles of carbon suspended in the flame to a greater incandescence,which increases the illumination.

My invention is adapted for and can be used on oil-stoves to increasethe heat-power of the same, and also for other stoves or furnaces orother heating devices.

The combination of a water-reservoir, a go wick, and wick-tube with theoil tube and wick of alamplam aware is not new. Itherefore do not claimsuch, broadly; but

What I do claim is- 1. The combination, in an Argand lamp, of anoil-reservoir, a central tube extending through the same,awater-reservoir below the oil-reservoir, a capillary wick-tubeextending through the central tube and communicating with the saidwater-reservoir, a button having a heat-transmitting stem extendingthrough or partly through the wick in said capillary ceive 2t hollowwick and communicate with 10 v the said water-reservoir, and a but-tonhaving a heat-transmitting stem adapted to pass into said wick andwater-tube, as and for the purposes described.
